Just a tidier job with ev ultra 👌 would have a joint box on the outside, also where it goes up the wall to db, that would look crap in a twin and earth with a data stuck to the side of it. Could have put some white trunking there but would have to be super wide due to the flat 90 bending radius
Section 443 states that surge protection should be installed where over voltage could result in serious injury or loss of life, so as the zappi uses PEN fault protection over voltage could cause degradation of the PEN fault protection device and cause it not to operate under loss of PEN conditions, therefore I believe surge protection is required.
You have to install SPD unless they opt out. It isn’t a requirement. Realistically, if there ever was multiple surges, the SPD will blow and be useless for the next surge as no one checks them. So I get why they aren’t set in stone like RCD protection. Nice point raised though
@@finneyelectrical your wrong, you can only omit the need of an SPD if a risk assessment is carried out where transient over voltage is unlikely or the cost of fitting such a device out ways the damage caused to equipment connected.
Pen fault protection isn’t used for over voltage, it’s used for a loss of the neutral conductor so in this instance the metal work would become live in a TNCS installation. Some manufacturers state an SPD must be fitted. So to comply with installation practices for the charger your fitting the customer not wanting it doesn’t cut the mustard 🤠👍
Nice job
Top electrician
Thank you! Was a fun one this one ☝️
Why wouldn't you use a 10mm T&E in that trunking with a cat5 to a junction box and then the swa?

Out of interest why didn’t you install an SPD?

Just have to offer it
